APPARATUS FOR EJ ECTING ASHES FROM VESSELS.

SPECIFICATION forming part of Letters Patent No. 483,770, dated October4, 1892.

Application filed March 29, 1892.

To all whom it may concern.-

Be it known that I, HORACE SEE, of the city and county of New York,inthe State of New York, have invented certain new and useful Improvementsin Apparatus for Ejecting Ashes and other Refuse from the Holds ofShips, which invention is fully set forth and 1l1ustrated in thefollowing specification and accompanying drawings.

The object of this invention is to render more efficient and certain theoperation of ashes-ejecting apparatus of the forms heretofore in use andto still further increase the usefulness of and convenience in using thesame by inclosing the main operative parts thereof within a close caseor box, which may be provided with suitable doors for opening andclosing certain parts of said box or cas- 111g.

In the accompanying drawings, Figure 1 gives a general side view of theapparatus, mostly in dotted lines, the parts thereby indicated beinglocated behind a bulk-head or partition, part of which forms one side ofthe box or casing containing the ejecting apparatus. Fig.2shows theparts of Fig. 1 in plan. Fig. 3 is an end view of Fig. 1, looking to theright.

In the figures the several parts are indicated by reference-letters, asfollows:

The letter A indicates an ashes receptacle or hopper, bounded bythe'dotted lines a a b b, Fig. 1, provided with a hinged cover 13. Saidcover is provided with hinges h and screw-bolts g for securing the sameupon a true or water-tight joint.

The dotted lines a a ff show the shape of the casing, of which thehopper A forms a part. The lower part of said hopper is connectcd to thelower part of the discharge-pipe C, and to the base of said pipe isconnect-ed the ejector-nozzle F of the ej ector-pipe D, provided with acook or valve E near said nozzle. Said pipe D is also provided with anair-vessel G near the cock E, which is provided with a handle 6. Thedrain-cock c is attached to the discharge-pipe C, so as to drain both itand the hopper A, when required, of any water that may remain thereinafter the apparatus has ceased to operate. The valve J is a reverse orvacuum valve attached to the Serial No. 426,913. (No model.)

discharge-pipe O to admit air and prevent the formation of a vacuum insaid pipe, which would impair the operation of the apparatus as anejector. The air-chamber G assists the ejector-pipe D in performing itsoffice while the ejector-pump (not shown) attached to the pipe D is inoperation.

The letter I-I indicates a door leading through the bulk-head y of acoal-bunker, and d a door opening into the case a afor access to thedrain-cock c and other parts within said casing. It preferred, thecasing a a ff may inclose, also, the air-vessel G, which is shown inFigs. 1 and 2 outside of said casing.

In Fig. 3 the air-vessel G is omitted for the sake of more clearlyillustrating other parts of the apparatus.

The casing inclosing this apparatus may be independent of any partitionor bulk-head; but I prefer, in embodying the apparatus on shipboard, toout an opening in a fire-room bulk-head separating it from a coal-bunkerat some convenient height from the floor and of sufficient size forshoveling therein the ashes. The hopper proper may then be built andsecured to the bulk-head on the coal bunker side thereof, the doorcovering the opening to the hopper being secured and operated from thefire-room and the handle of the ejectorcock being projected through thebulk-head forming one side of the easing into the fireroom.

Instead of an entire casing, if desired, a re cess may be formed in thebulk-head, which recess may be open only to the fire-room and the hopperplaced within said recess, the dis charge pipe leading, as beforedescribed, to and through the side of the vessel. It is preferable tolead the ejector=pipe D from the force-pump to a point or level abovethe hopper, and from such elevation then lead said pipe down to andconnect it with the ejectorcock E and ejector-nozzle F.

The operation of the apparatus as a whole is as follows: The door orcover B of the hop per A being closed, the drain-cock c is opened andany water that may be in the dischargepipe 0 is drawn 0E. This cockbeing again closed and the cock E in the ejector-pipe D also closed, theforce-pump (not shown) connected to said ejector=pipe is started and aninitial head or pressure of Water accumulated sufficient to force theashes up and overboard through the pipe G. Then suficient pressure hasbeen thus obtained, the ejector-cock E is opened, when the cover B maybe raised and the ashes thrown into the hopper A in suitable quantitiessuccessively. As the ashes fall to the bottom of the hopper and into thebase of the discharge-pipe 0 they encounter the current or jet of Waterfrom the ejectornozzle F, and by the force of said jet, assisted by therush of air into the hopper, are carried with the Water up the pipe G,and thence by and through it are discharged through the side of the shipoverboard, the point of discharge being either nearer to or, preferablyand more properly, a few feet above the surface of the water-line,depending upon the draft of Water and service-whether river or oceanservice-of the vessel. Should any of the ashes fail to reach the hopper,they will fall upon the fireroom floor, whence they can be re-collectedand thrown into the hopper or otherwise disposed of until the apparatusis again put in operation. The arrangement, location, and form of thehopper and its door are convenient for the rapid and ready deposit ofthe ashes therein by means of the ordinary shovels usedin the fire-roomfor shovelingcoal. When the ashes are all discharged, the door or coverB is again closed and secured before the ejector-pump is stopped. Thiswill prevent any backflow of Water out of the hopper due to the head ofWater which may remain in the pipe 0 when the ejectonpump is stopped. Inproviding the hopper A with its Water-tight door B, I obviate thenecessity of providing, and therefore may dispensewith, any valve in thedischarge-pipe C at the side of the ship, for no water can get into thehopper down the pipe 0 while the ejector-pump 1s 1n operation, and whenit is stopped, if any water should wash into and down the pipe 0 thewater-tight cover B Will prevent such water from entering into the holdor bilge of the ship or into any compartment thereof.

Having thus fully described my invention, I claim 1. An ashes-ejectorconsisting of aboxhaving its upper portion formed into an ash receptacleor hopper provided with a close-fitting door for opening and closing andlts lower portion forming a case inclos1ng e3ecting and dischargingconnections for said ashreceptacle.

2. An ashes-ejector consisting of a box having its upper portion formedinto an ash receptacle or hopper and its lower portion forming a caseinclosing discharging devices for said hopper, one side of said boxbeing formed by a wall, partition, or bulk-head provided with one ormore doors opening into the box, as and for the purposes set forth.

3. In an ashes-ej ector, the combinationof the following-named elements:an ash receptacle or hopper, a discharge-pipe therefrom, and anejector-pipe provided with a cool: or valve located in close proximityto the jet end of said pipe for opening and closing communicationbetween said pipes and with an air-vessel in close proximity to saidcook or valve, as and for the purposes set forth.
